The Texas Tenors will be backed by their four-piece band, in addition to the orchestra, which will have more than 40 musicians.

The spiritual “Amazing Grace” is on the bill, while a touch of Americana-themed material likewise is planned, according to the 43-year-old Collins.

The Texas Tenors are poised to “bring some really great popular and patriotic music to life,” according to Robert Vodnoy, conductor and music director of the Whiting Park Festival Orchestra.

“The arrangements are just spectacular,” Vodnoy, a Valparaiso resident, said. “The program is a deeply moving look at music that’s close to the heart of America, sung by three really wonderful tenors. They have really great voices.”

Collins and company are on their “RISE” tour, which takes its name from the trio’s 2017 album.

The disc features country-edged pop tunes such as the Eagles’ “Desperado” and John Denver’s “Thank God I’m a Country Boy.”
